In theory the answer is 240 tiles but this assumes that the area is "well behaved" and, if not, that you are prepared to use all the offcuts to fill bits in mosaic-style. A shape which in 17 inches wide, for example, will require a lot more pavers.

80 if the tiles are 12x12 - 12x12 is one square foot covering 80 you would need 80 tiles
144 square feet.
12" x 12" = 1 square foot, so you need 452 of them.

Since a 12x12 tile is one square foot, then 38 12x12 tiles will cover 38 square feet.
You would need 320 pavers to cover 160 square feet with 6x9 pavers, assuming each paver covers 0.5 square feet.
195 12 inches x 12 inches is 1 square foot
it will cover a 12x12 room
144.63 pavers
Any reason why it shouldn't be 220, apart from the shape of the area?
4.5 pavers will cover 1 sq foot. So 4.5 x 360 =1620 pavers
144 square feet. To calculate square feet simply multiply length by width - the result is the area in square feet.
